To all Lu/rom t may concern:

Be it known that I, `WILLIAM H. PIKE, dr.,

Ia citizen of the United States, residing at South Orange, Essex county, State of NewA Jersey, have invented certain new and useful Improvements in Attachments for Addt ing and Recording Machines, of which the following is a specification.

ylhe present invention relates to improvements in combined adding and recording machines of that class in which at every actuation of therecording devices, the operating means of the accumulating devices is operated. lin the practical use of machines of this character, it is sometimes desirable to use the recording devices for securinga record of a number without accumulating the value of saidl number on the accumulating devices.

To provide means by which this may be accomplished is the particular purpose of the present invention.

The invention has for its object additional purposes which will be evident from the following description.

lin the accompanying drawings, the invention is shown as embodied in an adding and vrecording machine of the type or character illustrated and described in Patent No.

n to; Fig. 2 is a plan view of a portion of the 763,692, dated June 28, 1904; but it will be evident that the invention is not limited to use with a machine of the particular style illustrated.

1n the drawings ;-Figure 1 is a side'elevation of an adding and recording machine having the present invention applied theremachine, several parts thereof being removed as they are not necessary to an understanding of the present'invention; Fig. 3 is a de tail plan view of one member of the accumulating devices; Fig. L is a Avertical longia sector 4 carrying a plurality of type ,5'

adapted to be moved,loy thereciprocationof said bar 3, over a platen 6.I Atits forward end, each of the strips 3 is provided with a /rack 7 adapted to actuatea vpinion-8 of the accumulating devices, said pinions 8 being mounted in a swinging frame 9 by which they can be moved to and from position where they will engage the racks 7. The strips and their connected type-carrying sectors are moved in one direction by the action .of a cam plate 10 on a power shaft 11, which,

in the particular machine illustrated, is operated from a crank or handle 12; and with each strip is connected a spring 13 that acts to move said strip in a direction opposite that in which it is moved by the cam 10.

rihe swinging frame 9 carrying the pinions and indicating wheels of the accumulating devices is connected with one member of a toggle 14, which is connected by a link 15 with a lever '16, suitably fulcrumed on the .frame ofthe machine, and having a laterally projecting pin adapted to be engaged by two ears or shoulders 17 18, on a cam plate 19 mounted on the main shaft 11. At each actuation of said main shaft, the cam 1() will be moved to release the sectors L and the lower ends of the latter, under the inliuence of the springs 13 will move forwardly, the extent of movement of each strip 3 and sector- 4 being determined by the particular key 1, .associated with said strip, which is depressed. At the termination of such forward movements of the strips 3, the shoulder or ear 17 of the cam plate 19 will actuate the lever 16, and through the link 15 and toggle 14 move the swinging frame 9 to cause the pinions 8 to engage with the racks'7. During the return movement of the main shaft 11, the strips- 3 will be moved rearwardly by the action of the cam plate 10, the pinions 8 will be turned 4by the racks toan extent corresponding to the previous forward movement of the lat-- ter, ard the number represented by the depressen key or keys 1 will be accumulated, such ntnber having been recorded by the recording devices at the completion of the forward movement of the strips 3. At the completion kof this rearward movement of the strips [3,] the shoulder` 18 will -engage the lever 16 and break the toggle when springs 20 willy act to raise the swinging frame 9 to lift the pinions 8 from engagelmentwithithe racks 7. rlhe operation thus brieydescribed is believed to be sutlicient for the purposes of explaining the present invention, the detailed operation of the Q y reader-s machine illustrated being clearly set forth in the patent hereinbefore referred to.

From the foregoing, it will 'be seen that i at each actuation of the handle 12, in the suitably fulcrumed on the framework of the machine, 'and carries a yielding plate er finger 22, adapted to be moved into the path p of the lever 16. Normally a spring 23 holds said lever 21 in the position shown in liigs. 1 and 5, where the finger 22 is held beyond the forward limit of the path of movement of the lever 16. lf, however, said lever 21 be movedinto the position shown in Fig. 6

and held there, said finger 22 will be engaged by the lever 16 as the latter moves forwardly to straighten the.toggle 1li and connect the pinions 8 of the'accumulating devices with their operating racks. At' the termination of such forward movement of the lever 16', the free end of said spring linger 22 will be deflected from its normal position and the finger placed under such tension that the instant the shoulder 17 is withdrawn from engagement with the lever 1G at the com mencenient of the rearward movement of the power shaft 11, said finger 22 will force the lever 16 rearwardly instantly opening the toggle 141 and allowing the pinions of the accumulating devices to return to their normal elevated position before any rearward movement of the racks 7.-l That is, if the upper end of lthehandle'21 is drawn forwardly and is held in this' position dur-ing an operation of the main operating handle 12, t e number represented by the depressed key or keys 1 will be recorded by the recordingdevices, but will not be accumulated by the machine. The lever 21 also serves another function. When it is-operative, as above described, al laterally projecting lip or foot 24 thereon is beneath the free end of a link 25 which is adapted to be depressed when'either thefsub-total key 26 or total lrey 27 is operated. .'iis'explained in said patent, when it -is desired' to take a sub-total, that I is to record the total of the amounts or items previously recorded and accumulated by the machine, and at the same time to retain such tot-al on the accumulating devices, the key 26 is depressed prior to operating the handle 12. In thus depressing the ley 26, the link 25 is pulled vdown to engage the stud or pin on the lever 16, and as said linlr is connected with a plate 28, that is rocked by a stud 29 on the cam plate 19 on the commencement of the movement of the power shaft 11, the toggle 141 is straightened and the pinions 8 of the accuinulating devices brought .into engagement with their operating racks prior to the beginning of the forward movement of thejstrips 3, and said pinions are maintained inA engagement with said racks until, at the completion of the return movement of the handle 12, the shoulder 18 on cam plate 1) operates the lever -16 to open the toggle 14. During the forward movementof the strips. 3 with the parts thus positioned, it

will be seen that the pinions S of the accumulating devices will be turned in a reverse direction to that in which they have been previously moved, the extent of such movement in the case of cach pinion corresponding to thenumber of steps which such pinion has previously been turned from its normal position. operates a stop for limiting such reverse movement when the wheel has been returned 'to its normal or zero position. r1`he move`- ment of each sector l-'will of course correspond directly to the extent of movement of its connected strip 3 and therefore the recording mechanism will indicate the total of the items previously accumulated by the turning of the pinions 8. During the return movement of the strips 3, under the influ ence of their springs 13, the pinions S remaining in engagement with the racks 7, each of said pinions will berestored to the That'is, with- .each `pinion coposition which it occupied p\rior to operating the machine' with the key 26 depressed and ,therefore at the. termination of such operation the accumulating devices will still indicate the total which has been recorded'. Such operation is designated as the taking of a sub-total. vWhen, however, it is desired to record the total of the items previously recorded and accumulated,- and at the same time to restore the indicators of the accumulating devices to Zero position, the key 27 is depressed before operating the handle 12. This causes thelink 25 to en gage with lever 16 prior to the beginning of the movement of the cam plate 19, so that the pinions 8 are engaged with their operating racks prior to the forward movement of the strips 3. Therefore during such forward movement of. the strips the pinions 8, will, as above described, berefurned to zero position and the recording devicesl actuated to record the total of the previously accumulated items. If the parts remain in this position, so that the pinions S are in engagement `with the rack 7, during the return movement of the strips 3, the effect will be,

as above described, to restore the pinions to the positions in4 which the accumulating insane mechanism will indicate the sum ofthe pre-I with will be moved rearwardly by reason of a stud or pin 29 on the cam plate 19 rocking the plate 28, by engaging with a dogA 30- thereon, and the link 15 will be drawn rearwardly opening the toggle and perinit-v ting the pinions 8 to rise from engagement with their operating racks. By this operar tion therefore the'accumulating devices will be left at zero following the operation of the machine with the key :27 depressed, during which operation the total of previously accumulated items will be recorded. is

.above noted, when the lever 21 is .swung forward, lits laterally projecting foot 24 is brought into position beneath the link 25, and. therefore it is impossible for said link tomove downwardly into engagement with the stud on lever 16, and consequently neither the sub-total key 26 nor total key 27 is operative to effect any result when the lever 21 is in the position shown in Fig. 6. This is an important feature, as without it an operator might unintentionally clear the machine or take a total while intending merely to record an item without having the value thereof accumulated by the accumulating devices.

As shown clearly in Figs; 2 and 3, the laterally projecting foot 24 of the lever 21 is provided with a slot through which the lever 16 extends, so that while it affords a hrm and positive stop preventing downward movement of the link 25,.it does not inter fere at all with the forwardvmovement of the lever 1G.
